One Year Clinical Evaluation of Pressed BioHPP Polyether Ether Ketone (PEEK)-Based Versus Zirconia-Based Single Crowns

Patient Satisfaction Clinical Trial

Official title:
One Year Clinical Evaluation of Pressed BioHPP Polyether Ether Ketone (PEEK)-Based Versus Zirconia-Based Single Crowns (Randomized Controlled Clinical Trial)

Clinical Trial Summary

The clinical performance (using the modified Ryge criteria) and patient satisfaction ( using VAS questionnaire) of pressed BioHPP PEEK based posterior single crowns compared to zirconia based crowns are questionable as the peek is considered as a new material and need to be tested for future clinical application.

Clinical Trial Description

The study is held to evaluate the clinical performance (using the modified Ryge criteria) and patient satisfaction ( using VAS questionnaire) of pressed BioHPP PEEK based posterior single crowns compared to zirconia based crowns after one year follow-up. Patients requiring posterior single crowns are collected. After teeth preparation to receive single full coverage crowns, secondary impressions were taken. The patients were divided randomly into two groups ;one group will receive pressed BioHPP PEEK single crowns (the intervention) and the other group will receive veneered zirconia single crowns (the control). Fracture of restorations (1ry outcome) using modified Ryge criteria and the marginal adaptation (2ry outcome) using modified Ryge criteria and finally the patient satisfaction (3ry outcome) using a questionnaire, all outcomes will be evaluated every 2 months with total period of follow-up of one year. ;
